Installing P-trap.Fig. 9.
Construct a P-trap using the plastic T-fitting provided.
Cut two lengths of 1/2 in. ID hose and connect each 1.
drain fitting to the end of the T-fitting.
Position the center leg of the T-fitting so it points upward.2.
Connect the drain line to the center leg and tape it in 3.
place to prevent any kinks. See Fig. 9.
This creates a trap that will hold some condensation
and prevent odors from being drawn up through the
drain hose into the unit. If the unit is installed during a
season when it is unlikely that condensation will form,
fill the trap with tap water.
